A
PromiseWorker is a
ChromeWorker except instead of calling
postMessage() to send a message, you call
post(), which returns a
Promise. JavaScript files imported into the worker scope and main thread scope which allows posting to the worker and receiving in the form of a
promise. Like
ChromeWorker objects,
PromiseWorker is mostly used for
js-ctypes but it is not limited to that. There is no
XPCOM access, similar to
ChromeWorker. This answers the question "When should I use a
PromiseWorker?", and the answer is, whenever you would normally use a
ChromeWorker, but want
postMessage to return promises.
